Why is it ok to bomb Mosul but not Aleppo?

For the past few weeks, British news-papers have been informing their readers about two contrasting battles in the killing grounds of the Middle East. One is Mosul, in northern Iraq, where western reporters are accompanying an army of liberation as it frees a joyful population from terrorist control. The other concerns Aleppo, just a few hundred miles to the west. This, apparently, is the exact opposite. Here, a murderous dictator, hellbent on destruction, is waging war on his own people.

Both these narratives contain strong elements of truth. There is no question that President Assad and his Russian allies have committed war crimes, and we can all agree that Mosul will be far better off without Isis.

Nevertheless, the situations in Mosul and Aleppo are fundamentally identical. In both cases, forces loyal to an internationally recognised government are attacking well-populated cities, with the aid of foreign air power. These cities are under the control of armed groups or terrorists, who are holding a proportion of their population hostage. …

As always, the media is the problem:

This episode highlighted the double standard about western reporting of these terrible problems. In Mosul, western reporters travelling with the invading Iraqi army publish pictures of joyful populations liberated from the jihadists. In Aleppo, the attempt to free the city from al-Qaeda control is portrayed as a remorseless attack on the civilian population.
